Ninety six kindergarten age children participated in a study which assessed the effects of three procedural factors on performance in identity and equivalence conservation tasks. (SB)

A total of 72 kindergarteners received eight conservation of number trials which varied in the degree of perceptual support for one-to-one correspondence (four levels) and type of stimuli (toy animals or corks). A between-subjects variable was the method of presentation (standard conservation presentation, a partially fixed array, or a fixed…

This study examines the extent to which modeling facilitates transformational problem solving in mathematics for children in kindergarten and first grade. Subjects were 20 children selected from each level. They responded to two problems for each of four problem types (counting on, story problems, quantitative comparisons, and ordination) under…

This paper presents a study designed to clarify the role of perceptual-attentional factors in the development of conservation, and relates the results to procedures for assessing conservation. Subjects were 192 first and second graders. The number and type of perceptual cues in the conservation of liquid quantity task were systematically varied.…

Four groups of kindergarten children were involved in a pretest-posttest experiment comparing verbal cued, visual cued, verbal rule sulpplemented instruction on conservation tasks. Both language level and analytic sorting behavior were reliable predictions of number conservation performance in individual children. (Author/WY)
